Biology chapter 3

A cell that requires a lot of energy might contain large numbers of 

• lysosomes
• chromosomes
• mitochondria
• vacuoles

The organelles associated with plant photosynthesis are the

• chloroplasts
• vacuoles
• mitochondria
• Golgi apparatus

Which of the following led to the discovery of cells?

• computers
• electricity
• calculators
• microscopes

Which structure acts as a boundary between the outside environment and the inside of the cell?

• cell membrane
• nuclear envelope
• nucleus
• mitochondria

The genetic material that provides instructions for making proteins

• cytosol
• DNA
• cytoplasm
• a ribsome

Osmosis is a type of what?

• active transport
• simple diffusion
• endocytosis
• passive transport

What do chloroplasts and mitochondria have in common?

• digestion of cell wastes
• presence in all cells
• production of ATP
• absorption of light energy

The sodium-potassium pump

• is a carrier protein
• is located in the cytoplasm of a cell
• transports sugar molecules
• uses passive transport

When the volume of a cell increases, its surface area

• remains the same
• increases at a faster rate
• increases at the same rate
• increases at a slower rate

One difference between prokaryotes and eukaryotes is that prokaryotes do not have

• DNA
• cytoplasm
• a cell membrane
• a nucleus
